Department of Transportation August 22, 2011 – Federal Register Recent Federal Regulation Documents

The FHWA has approved a request from Maryland Transportation Authority (MDTA) to temporarily close a portion of I-395 (just south of Conway Street in Baltimore City) from approximately 7 p.m. on Thursday, September 1, 2011, until approximately 6 a.m. on Tuesday, September 6, 2011. The closure is requested to accommodate the construction and operation of the Baltimore Grand Prix (BGP), which will use the streets of downtown Baltimore as a race course. The approval is granted in accordance with the provisions of 23 CFR 658.11 which authorizes the deletion of segments of the federally designated routes that make up the National Network designated in Appendix A of 23 CFR Part 658. The FHWA published a Notice and Request for Comment on June 28, 2011, seeking comments from the general public on this request submitted by the MDTA for a deletion in accordance with 23 CFR 658.11(d). No public comments were received.

This notice provides information regarding the FHWA's finding that a Buy America waiver is appropriate for the use of non-domestic 5 \3/8\'' stud link chain for a Recovery Act bridge replacement project in Larose, Louisiana.

In compliance with the Paperwork Reduction Act of 1995 (44 U.S.C. 3501 et seq.), this notice announces that the Information Collection abstracted below has been forwarded to the Office of Management and Budget (OMB) for review and approval. The nature of the information collection is described as well as its expected burden. The Federal Register Notice with a 60-day comment period soliciting comments on the following collection of information was published on May 27, 2011, and comments were due by July 26, 2011. No comments were received.

We are adopting a new airworthiness directive (AD) for the products listed above with certain part number (P/N) fan rotor spinners installed. This AD requires removing from service certain fan rotor blade retainers, and removing from service the fan rotor spinner support that was installed with those fan rotor blade retainers. This AD was prompted by a fan rotor spinner support found cracked at the attachment lugs. We are issuing this AD to prevent high-cycle fatigue cracking of the fan rotor spinner support attachment lugs, leading to separation of the fan rotor spinner assembly, uncontained failure of the engine, and damage to the airplane.

We propose to adopt a new airworthiness directive (AD) for the products listed above. This proposed AD results from mandatory continuing airworthiness information (MCAI) issued by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as:

This action establishes a high altitude area navigation (RNAV) route, designated Q-37, extending between the Pueblo, Colorado, VHF omnidirectional range/tactical air navigation (VORTAC) navigation aid and the Fort Stockton, Texas, VORTAC. The new route provides pilots and air traffic controllers with an efficient alternate route around potentially constrained airspace during convective weather events in west Texas.

This action proposes to amend Class E Airspace at Jacksonville, NC, as new Standard Instrument Approach Procedures have been developed at Albert J Ellis Airport. This action would enhance the safety and airspace management of Instrument Flight Rules (IFR) operations at the airport.

This action establishes Class E Airspace at Forest, VA, to accommodate the new Area Navigation (RNAV) Global Positioning System (GPS) Standard Instrument Approach Procedures serving New London Airport. This action enhances the safety and airspace management of Instrument Flight Rules (IFR) operations within the National Airspace System.

This action revises the operating rules for flight in icing conditions. For certain airplanes certificated for flight in icing, the new standards require either installation of ice detection equipment or changes to the airplane flight manual to ensure timely activation of the airframe ice protection system. This action is the result of information gathered from icing accidents and incidents. It is intended to increase the level of safety when airplanes fly in icing conditions.

This rule establishes, amends, suspends, or revokes Standard Instrument Approach Procedures (SIAPs) and associated Takeoff Minimums and Obstacle Departure Procedures for operations at certain airports. These regulatory actions are needed because of the adoption of new or revised criteria, or because of changes occurring in the National Airspace System, such as the commissioning of new navigational facilities, adding new obstacles, or changing air traffic requirements. These changes are designed to provide safe and efficient use of the navigable airspace and to promote safe flight operations under instrument flight rules at the affected airports.

We are adopting a new airworthiness directive (AD) for the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) issued by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as:

We are adopting a new airworthiness directive (AD) for the products listed above. This AD requires repetitive inspections for cracking of the lower rear spar caps of the wings, and related investigative and corrective actions if necessary. This AD also requires repetitive inspections of certain repaired areas. This AD was prompted by reports of cracking of the wing rear spar lower cap at the outboard flap and inboard drive hinge at station Xrs=164.000; the cracking is due to material fatigue from normal flap operating loads. We are issuing this AD to detect and correct such fatigue cracking, which could result in fuel leaks, damage to the wing skin or other structure, and consequent reduced structural integrity of the wing.
